MDX YTD 计算度量

Question

I'm still new to MDX and I'm trying to get some basic functions to work in my SSAS cube. Can you guys point out what I'm doing wrong here? I've added a calculated measure to my cube with the following code:

CREATE MEMBER CURRENTCUBE.[Measures].[Amount YTD]
AS
  AGGREGATE(
    YTD([OrderDate].[Calendar].CurrentMember)
   ,[Measures].[Amount]),
VISIBLE = 1, ASSOCIATED_MEASURE_GROUP = 'MyMeasureGroup';

After that I'm trying to get some data going...

SELECT 
NON EMPTY
{
  [Measures].[Amount]
, [Measures].[Amount YTD]
} ON COLUMNS,
NON EMPTY
{
  [OrderDate].[Month].ALLMEMBERS *
  [Product].[Product Group].ALLMEMBERS 
} ON ROWS
FROM (SELECT ([OrderDate].[Year].&[2014-01-01T00:00:00]:
              [OrderDate].[Year].&[2015-01-01T00:00:00]) ON COLUMNS
FROM [SalesOrderIntake])

This is the output I'm getting:

I'm not seeing any errors in my Output messages, which makes it difficult for me to figure out what is acting up. Hoping you guys can help me out on this one.

FYI: the actual select is just for testing purposes. I just want to get that YTD running. I've tried several things and it always comes out empty, so I was hoping to get some actual errors if I would query it directly in SSMS instead of using a BI tool. Also, the OrderDate dimension is a generated Time dimension which was provided to me by VS.

Answer 1

In your query you're using what looks like an attribute hierarchy:

[OrderDate].[Month].ALLMEMBERS

Whereas the measure uses the user hierarchy:

[OrderDate].[Calendar]

If you use Calendar in your script does it work ok?

Answer 2

#Error usually crops up when there are run time errors in MDX code. I could think of one scenario where the error might crop up. You are using [OrderDate].[Calendar].CurrentMember in the calculated member. But if instead of one, there are multiple members from this hierarchy in scope, it will throw an error.

The below is a scenario from Adventure Works.

with member abc as 
sum(YTD([Date].[Calendar].currentmember), [Measures].[Internet Sales Amount])

select abc on 0
from [Adventure Works]
where {[Date].[Calendar].[Date].&[20060115], [Date].[Calendar].[Date].&[20060315]} 

PS Thanks to @whytheq for teaching me this trick of checking this error by double clicking the cell :) Cheers.

Answer 3

I know, its an old post, but in the interest of posterity..

The correct approach is :

Aggregate
(
    PeriodsToDate
    (
        [OrderDate].[Calendar].[Fiscal Year]
        ,[OrderDate].[Calendar].CurrentMember
    )
    ,[Measures].[Amount]
)
